Bonds payable to whomever holds them are called _____ bonds or unregistered bonds.
Hatshy [7]

Bonds payable to whomever holds them are called bearer bonds or unregistered bonds.

<h3>What is bearer bond ?</h3>

Bonds that have no registered owners are known as bearer bonds. Instead, the bond is owned by whoever "bears" (or has possession of) it. Bearer bonds, sometimes known as coupons, have coupons that bondholders can detach and present to receive interest payments.

<h3>What are interest payments ?</h3>

An interest rate is the amount of interest that is payable each period stated as a percentage of the amount that was lent, deposited, or borrowed. The principal amount, interest rate, frequency of compounding, and duration of the loan, deposit, or borrowing determine the total amount of interest on a sum that was lent or borrowed.

What are the molality and mole fraction of solute in a 22.3 percent by mass aqueous solution of formic acid (HCOOH)?
Vanyuwa [196]

Answer:

Mole fraction for solute = 0.1, or 10%

Molality = 6.24 mol/kg

Explanation:

22.3% by mass → In 100 g of solution, we have  22.3 g of HCOOH

Mass of solution = 100 g

Mass of solute = 22.3 g

Mass of solvent = 100 g - 22.3g = 77.7 g

Let's convert the mass to moles

22.3 g . 1mol/ 46 g = 0.485 moles

77.7 g. 1mol / 18 g = 4.32 moles

Total moles = 4.32 moles + 0.485 moles = 4.805 moles

Xm for solute = 0.485 / 4.805 = 0.100 → 10%

Molality → mol/ kg → we convert the mass of solvent to kg

77.7 g.  1 kg / 1000g = 0.0777 kg

0.485 mol / 0.0777 kg = 6.24 m

Are all metals magnetic?
pickupchik [31]

✅Magnetic materials are always made of metal, but not all metals are magnetic. Iron is magnetic, so any metal with iron in it will be attracted to a magnet. Steel contains iron, so a steel paperclip will be attracted to a magnet too. Most other metals, for example aluminium, copper and gold, are NOT magnetic.
